3YM30 propeller questions
What size propeller suits a Yanmar 3YM30?
It depends on the gearbox ratio behind it (documented installations most often run 2.62:1, 2.64:1, 2.21:1) and the boat it pushes. Power and max RPM set the optimum diameter; the ratio converts engine speed to shaft speed. The Builder runs the numbers and an engineer verifies.
Which propeller family do Yanmar 3YM30 owners fit?
Documented Yanmar 3YM30 installations run Autoprop H5, Varifold 2-blade, Varifold 3-blade — the split follows boat type and usage rather than the engine itself.
Does the Yanmar 3YM30 come in shaft and saildrive versions?
Both are documented: 214 shaft and 110 saildrive installations. The propeller differs (hub vs spline fitting) so tell us which yours is.
